Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix DP3B against official Mallory Sonalert documentation to confirm terminal block termination and slow double pulse functionality. Ensure the operating voltage remains within the 28 V to 48 V DC specification. Confirm that the 40 mA current rating is compatible with the driving circuit capacity. Check for required certifications such as cUL or UL depending on the target market regulations.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a distinct slow double pulse signal is required for industrial alarms. The 2 kHz frequency provides clear audibility in noisy environments. The 95 dB SPL ensures sufficient volume for large facilities. Verify that the panel mount form factor fits the enclosure design constraints. Consider the 40 mA power consumption for battery-backed or low-power system designs.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of electronic alarms, which are characterized by their compact size and high reliability. The SCE line typically includes various tones and voltage options to suit different industrial signaling needs. Mallory Sonalert manufactures these devices for demanding environments requiring consistent performance.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official cross-reference guides for direct equivalents. Verify that any substitute matches the 28-48 VDC input range, 40 mA current draw, and 2 kHz slow double pulse output. Ensure physical dimensions allow for the same panel mounting configuration.
